IMPROVEMENT In FAUCETSS.

I Specification forming partfof LettersPatent No. 46,727fdnted March 7,1865.

Y and useful Improvements in Faucets'3'and I do hereby declare that thefollowing description,`taken in connection with the accompanying plateof drawings, hereinafter referred to, forms a full and exactspecification of the. same, whereinI have set forth the nature andprinciples of my said improvements by which my. invention. may bedistinguished from all others of a similar class, together with suchparts as I claim and desire to have secured to me by Letters Patent.

The present invention relates to certain new and useful improvements infaucets contemplating two distinct features -tobe obtained, the rst ofwhich is to prevent leakage and the-second to ei'ect a' commingling vofair with liquids, more especially fermented ones, so as to produceebullition.

My improvements consist in so forming and arranging air spaces orchambers with regard to the chamber or pipe through which the liquidisdischarged that the downward passage. ofthe latter creates a vacuum orpartial vacuum in the faucet and causes air to rush into and through the'said air spaces or chambers and mix with the liquid pasing out, thetendency,'n1or eover, of this downward current of air beingto check theupward pressure of the liquid and thus prevent leakage at the valveor'screw-,plug

My improvementsare represented in the accompanying plate of drawings, ofwhich Figure l is an exterior view of my'improved faucet. Fig. 2-is acentral vvertical longitudinal section of the-same. Fig. 3 is a view ofanother form of faucet, and Fig. 4 is `a central vertical longitudinalsection of the same. Fig. 5f illustrates the principle of ac` tion inthe several forms shown.. Fig. 6 is.

, a horizontal section taken in the plane of the line A B. p

aa a in the drawings represent the main or outer tube of a faucet,connected with which is asupply' tube or pipe,b b, and exit tube or pipec c. The supply-tube .o vb extends upward some distance above itshorizontal axis into the main tube a a, forming an extensiontube, d d,and leaving a chamber, e e, between the tube d d and the outer tube,aa.. Within the outer tube, a a, and extending from near l its topdownward to the top of the extensiontube d this a ring,`ff, so connectedwith the outer tube, a a, at different points as to form between it andthe ringf f an annular air space or spaces or chambers g g, On the innerside of the ring f j a female screw-'thread is cut. h h is a screw-plugor valve having a leather or other washer, i i, attached to its bottomand comin g to a seat or bearing on the top of the extension-tube d d.`It will be observed that the screw-plug h-vh, instead of Working in theouter tube, a, a,- plays up and down in the screw-thread'eutonthe insideof the"ring'j'f.` The stem k lc' of the screw-plug h 71. turns looselyin a cap for top piece, l l, that screws over the top of the outer tube,a a.

From the foregoing description it will be' observed that when thescrew-plug or valve h It is raisedthe water or other liquid passes upthrough and over the top of the extensiontube d d, into the chamber ee,and out through the exit or delivery pipe o o. The downward passage ofthe water through the chamber ee and exit-pipe c c creates a vacuum orpartial vacuum in the same and causes a current of l air, freelyadmitted to the` chamber m m, to pass from the latter down through theairA spaces g g into the chamber e e and mingle with the liquidipassingthrough the chamber e e and the exit-pipec o, thus not only serv-,p

ing to counteract the tendency of the liquid to pass with anyconsiderable degree of force upwardbetween the threads of the, screw'plug h hand those of the ring f f, and to draw downward through theair-spaces g g, what little liquid might so escape, but also to thoroughly mix the 'air and liquid together so as to cause agitation inthelatter, which is often desirable in fermented liquors. l

Having t-husdescribed my improvements, whatI claim as my invention, anddesire to have secured to me by Letters Patent, is`

1. The spaces or chambers to which air has ree access around lthe tubethrough which the liquid passes in such a manner -that extension-tube dd, aud lair spaces or cham-v wlion a vacuum or partial vacuum iscreated. bers g g, arranged and voperating with regard in the chamber inwhich the said tube is loto each other substantially as described.

cated, by the downward current of the said HERMAN STRATER, JR. liquid,the air and liquid will be eommin'gled, Witnesses substantially asspecified. JOSEPH GAVETT,

2. The combination of the screw-ping h. h, SAML. M. BARTON.
